Deleted Emails By Error

hi guys, this is my first post here… i need help urgently…

i was turning on my PC, started to check emails and of course, Anti-spam did the initial check. After i went through the Quarantine Database and configured whose emails are acceptable or rejected as spam, i went back to Outlook but i can’t see the emails that i’ve accepted in my Outlook inbox. i check the Authentication Database again to confirmed that the emails i accepted are in the right option, it was. but after clicking receive/send, i still do not see the emails in the inbox… i suspect that Anti-spam might have deleted the emails accidently.

is there anyway i can retrieve the emails back?

Some are pretty important for my work.

Thank you very much.
